I claim:

1. A lplate valve comprising avalve seat having ribs forming passage-Ways,` grooves in said valve seat having diverging sides forming vseating surfaces, rigid valve plates cooperating With the seatingl surfaces for cont-rolling the passage-Ways, said valve plates being supported by the bottoms of the grooves, and springs secured at one end to the ribs adjacent the inlet openings of the passageway and at their other ends to the valve plates for holding the valve plates on the seating surfaces.

f 2. A plate valve comprisin-g a valve seat assaOe-Wa s Grooves in said valve to one end of the valve seatl ing surfaces, rigid valve plates supported by the bottoms of the grooves and adapted to control the passage-Ways, means secured toretain the valve plates in the grooves, and means supported by said means extendingk into the grooves for limiting the degree ofopening of the valve plates.

3. A plate valvejcomprising a valve seat having passage-vvays, grooves across an end face lof thevalvevseat, said grooves having diverging sides forming seating surfaces, rigid valve plates cooperating with the seating surfaces to control the passage-Ways, springs for holding the valve seating' surfaces, and means supported by one end of the valve seat having integral means extending betweenk adjacent valve plates to form stops for the valve plates.
